Browns. SYSTEM.

Application filed. October 23, 1909.

To all whom it may concern Be it known that 1, CHARLES ,E. CLARKE, a citizen of the United States, residing in the city, county, and State .of New York, havemade a certain new and useful Invention in Blower Systems, of which the following is a specification.

This invention relates to blower systems, and particularly to such systems as applied to locomotive round houses, sheds or the like.

The object of the invention is to provide a blower system wherein the locomotive fire box or furnace chamber may be placed under the influence of an induced draft to facilitate and hasten the firing up of the locomotive.

A further object is to provide a blower system with means for absorbing the heat from the heated medium, gases or other products of combustion drawn from a locomotive or other source.

A further object is to provide means for automatically regulating and controlling the supply of the heating medium and to utilize the medium heated thereby.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claim. 5

Referring to the accompanying drawings and-to the various views and reference signs appearing thereon, Figure 1 is a View in elevation somewhat diagrammatic of a blower system embodying my invention, showing the application of the same to a locomotive. Fig. 2 is a .top plan view of the same, the locomotive being omitted and'a part of the automatic regulating means in section. Fig. 3 is a broken detail view of a portion of the blower system parts broken out and parts in section, showing an economizer, or heat absorbing device employed in connection with the principles of my invention. Figs. 4 and 5, are broken detail views, in section of parts of the automatic controlling means.

The same part is designated by the same reference sign wherever it occurs throughout the several views.

When locomotives arrive at a terminal station it is customary to draw ofi' the steam from the boilers thereof, and, oftentimes, to

draw off the heated water from the boiler,

and also to draw ofi the heat from the firebox or furnace chamber, for the purpose of cleaning out the locomotive and supplying its boiler with fresh water and its furnace chamber with a fresh fire-bed. The heat from the fire boX is ordinarily carried ofi to the atmosphere through the smoke stack of the round house or shed, or otherwise, and

is consequently wasted. Moreover, in starting up the fire inthe fire box, or in filling the locomotive boiler with fresh water, it has been a common practice to employ a cold air draft in the one case and cold fresh water in the other, with the result that the firing up operation is retarded, and the steam generation is delayed.

It is among the special objects of my prescut invention to provide a blower system in Y which is employed an economizer arranged to absorb the heat from the fire box products or other source and to apply the absorbed heat to a medium, such as air or water,

which can be utilized for any purpose for which such heated medium .is adapted, such for instance, as for heating the round house or shed, for supplying the boiler of the loco motive initially with heated fresh feed water, where water is the medium heated, or for supplying a draft of heated air, where air is the medium heated, to the fire box of the locomotive in starting up the fire therein, thereby facilitating and expediting the operation of firing or if getting up steam,

economizing in time and-in fuel and saving and turning to useful account what has been before wasted andlost. These obj ects and purposes, and others analogous thereto, may be carried out in a wide variety ofways and by means of a wide variety of different arrangements. While, therefore, I have shown, and will now. describe a form and arrangement of devices which I have found to be eflicient for the purpose, my invention in or other convenient communication with the V main pipeline are a plurality of extensions D, each adapted to be brought intoqregister smokestack of a locomotive as shown Located in the line ofthe main pipe l1ne 1s an economizer F, which may be of an-y sultable, convenient or desired constructiom'and through which is to be circulated a suitableheat absorbing medium, such as water or air,

the heated products forced through the main pipe line circulating around and about the piping of'the economizer. Inthe arrangement shown, water is circulated through the econ- V omizer and absorbs the heat from the heated delivered from the economizer F, through any suitable connection pipe G, or'to a heatproducts drawn from the locomotive fire: box, 'o'r other source, the heated water belng ing coil T, or other point wherethe heated mediumfis to be utilized; 1 7

It may sometimes be desirable .to automatically control and regulate the amount of the heated gases or other'products' to be circulated through the main pipe line and the economizer. I propose to accomplish this result from the heated products themselves. To this end I employ an auxiliary connection H, from any desired source of heat such as the smoke flue of the lusual plant furnace or other source and leading, to

' the main pipe line; Inthis auxiliary con- I nection I place a damper J, and I provide means controllediby the-heated products in I the main pipe line system forautomatically operating the damper J, accordingto the re- 7 quirements, whereby more or less of the heated products maybe circulated around the economizer. Thus'in case the heated products from the fire box of a locomotive r so.

are not sufficient to attainthe degree of heat in the economizer the deficiency can be made up from the flues.- A simple arrangement I of means for effecting the automatic 'regula- 7 tion referred to is shown whereina cylinderv K,,is provided with a piston, the rod L, of which is connected to a crank arm M, mounted on the shaft which carries the damper J. Pressure medium issupplied to one end of" cylinder Kyfrom any convenient source. through pipe N, in which is located a valve for controlling the supply of pressure mediumto the cylinder K. 'This valve is arranged to be operated thermostatically by the heat passing through the main pipe system B. Thus, I have shown a device P, see Fig. 4, extending intothe' pipe B, and ,also into the casing R of the valve.

This device may be of suitable'metal or.

other material "influenced by the heat to which it is subjected whereby-according as I the heat'increases or decreases the said device expands or contracts and by the expansion or contraction of the same efi'ects the proper operationof 'the'valve, thereby permitting a' greater or less amount of pressure medium; tobe admitted to cylinder K, i

thereby; through. the resultingoperation of the piston therein, and its connections to valve J, permitting a greater or less amount of the heating medium to be drawn from the flue/S, and circulated around theeconomi zer as may be desired.

pose of being cleanedout and put in condition for the next run, an extension fD of the pipe line system is coupled to the'locomotive smoke stack, andthe heated products from the fire box are drawn off through the pipe system. Instead 'of' delivering these heated products to the power or round house chimneyor smoke stack, they are caused to first travel through theeconomizer through which is circulated a'heat; absorbing me- 7 dium, such-as airor water ,'and which ab sorbs the heat from the heated products, and is thereby enabled to save such heat and apply the same to usefulpurpose's"such as heating the building by 'coil 'as T, or heating the fresh feed water to be supplied to the boiler, or for any other purpose forr which it is adapted. In this ma-nnerthe boiler out and made ready 'to-r'eceive the fresh supply of clean feedwater, anda fresh fuel bed is built up in thefurnace firebox, and, if desired, in firing the fresh i-bed of fuel the heated air, if air. is the heat absorbing me dium' employed, maybe drawn through the fire box by reason ofthe connection of the pipe system with the locomotive Smokestack, thereby utilizing heated air instead of cold and the firebox of the locomotive,arecleaned air'fo'r draft purposes in'thefirexbox, and

hence greatly facilitatingand hastening the V firing operation. 1
